Axial periodicity around the origin | Polar or Tube |
Repetition in r is not permitted because of the method used to calculate the potentials in cylindrical geometry.
Cylindrical geometries are handled via a conformal mapping onto a Cartesian coordinate system in which an r-periodicity would be equivalent to an x-periodicity with non-constant intervals. This is technically difficult to deal with. Contact the author if there is a genuine need for such a periodicity.
